I removed the Fiama awning on my
Casita a few years ago. (I still have it if someone wants to make me an offer - it was probably used 3 times, and is in dry storage in my garage along with all the associated brackets and mounting hardware.) I won't even try to ship it anywhere due to the size and
weight, it's about 10' long, but if you want to pick it up here in western WA, I'll make somebody a good deal on it. First $500 bucks takes it. It's like brand new.
When I removed it, I just drilled out the old rivets and cleaned up all the previous awning mounting bracket sites and then put new rivets with white caps and sealant in the existing holes.
I now use a Clam 1660 pop-up for an awning/screen room. I never liked the awning, but I love the Clam. There have been at least a few threads on these Clam units in the forum here.
